MACHINE FOR FORMING LAClNG=-TiPSI Patented April 1'7, 1906.

Application filed June 8, 1905. Serial No. 264340.

Be it known that 1, CHARLES F. PINKHAM, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Machines for Forming Lacing-Tips, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object to provide a machine for the manufacture of composition tips of laces for shoes and like articles of the kind shown and described in United States Letters Patent No. 772,338 to Edwin M. S. Chandler. The tip there shown is produced by turning or tucking in the end of the tubular material from which the lacing is made, filling the turned-in end with some suitable flowing composition, and then subjecting the whole to pressure in dies of proper shape,

thus causing the filling material to set andto form a hard tip for the end of the lacin The machine described in this application is. intended more especially for forming the tip on one end only of 'a lacing; but in practice where a tip is required at each end of al'acingl propose to use another machine, similar to that described in my present application, but oppositely arranged and placed, which shall be simultaneously forming the tip on the other end of the lacing. I also propose to provide automatic feeding, measuring, and folding mechanism which shall supply the tipping macl' ines with portions of lacing of the desired length and which shall fold the lacing after the tips have been applied. These I contemplate shall form the subject of further applications for United States Let ters Patent.

lVly-machine is also adapted to be used for the production of other articles besides lacings which are composed of tubular fabric the ends of which are turned in.

The machine of my present invention is composed of several distinct groups of mechanism which cooperate to perform upon the lacing the necessary operations and to transfer the lacing. from one position to another automatically. through the machine is substantially as l'ollows: It is placed by the operator or fed from a reel into a position where it is seized by a The progress of the larirg is-then moved into the position Where the turning in takes place, the end of the lacing being dilated or distended during the turning 1n. wherethe distended portion is filled with the composition and the whole is compressed to form the finished lacing-tip.

It will thus be seen that the machine naturally divides itself into the following primary The lacing isthen moved to the dies,

groups of mechanism, viz: cutting mechanism, turning-in mechanism, filling or cementapplying mechanism, and compressing mechanism. Various transferring mechanisms,by which the lacing is moved from one group of primary mechanism to another, are also provided.

While I have shown my invention as embodied in a machine of particular form and structure, I believe my invention to be a very broad one, and I do not desire to limit myself to the particular form illustrated in the drawings and described in the specification, since the invention may be otherwise embodied without departing from its spirit.

The invention will be fully understood from the following description, taken in connection with the accompanying drawings, and the novel features thereof are pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a plan view of a machine embodying my invention. Fig. 2

.l teferring now to the (.lrawings, and particularly to Fig. 1. the frame of the machine is indicated at a, and the main shaft, a t, f). A series of cams c, (I, c,f, and t], which drive'the various parts of the machine and will be later described. are mounted upon the main shaft, which is. self tiriven by a pulley ft, upon which runs a. belt or chain. (Not neccssaiw to be shown.) The frame a of the machine is of convenient shape to support the various operative parts of the mechanisn'i and may be constructed. of a single piece of east-iron or may built up from a number of smaller pieces, as is most convenient.

As previously seen, the'maehine is divided into a imu'iher oi dill'erei'it primary groups of mechanism, each of which performs one of to c operations necessary for the completion of the finished tip, in my description I will follow the lacing in its progress through the ins'tcl'iine, describing each of these groups of mechanism, and will begin with the cutting n'ieehanism.

Referring now to Figs. 1, 2 7, and b, the lacing, which is fi tunposed o'f'a tubular fabric of the proper size, is indicated at It may bellied from a reel or laid into the proper position by hand. When in this position. it

A fixed knife 28 is attached to the frame of the machine in a suitable. manner, and a morable lilllft it! is secured to the left-hand side of the slideway 12. These knives sever the lacing from the piece if a continuous piece of material on a reel or other feeding means be used or clip off the end of the lacing preparatory to the turning-in process where the machine is fed by hand. The lacing is fed into proper position while the parts of the machine now being referred to arein the position shown. in Fig. 7 and are standing still. ltotationof the cam d causes the slid'cway 12 and the gripping member it) thereon to move forward and to pinch the lace i against the other gripping member 1 l, as seen in Fig. 8, th s movement being permitted by the slot 27 in the sli(le\\'a 12. The gripping member 10 applies a yielding pressure to the lace by. means of the spring It I, attached to the hook .on the gripping member 10 and to the stud .1.) on the slidewav 12. it will thus be seen that the lacingi is firmly held at. one point by the just-descrilml groupof members,which I will designate by A and will hereinaftereall the cutter-grimwr." The lacing i is held at a second point at the rightofthelirst-mentioned point. by a second group of members, which 1 willcall thesidegrippciand designatebyB. This side gripper B (see Fig. 19) consistsof a bracltct 4. attached to the slideway 112 b the screws ai d provided at its end with a ohcchertal surface 36. A movable jaw 37 is pivoted to the bracket 34 at 3b and is actuated at the proper time b the pivoted campiece it). A. spring 42 tends to pull the said cam-piece it) toward the under side of the braclact 34 as soon asthe side gripper l) is moved toward the tnrning-in position far enough to release the lower end of the campiece 40 from the stop 42]. The jaw 37 is provided with a finger 37], which engages a cam-surface on the cam-piece 4t) and causes gear-teeth and that movement of the 'ampiece it) in one direction opens and in theother direction closes the movable jaw 37. it will also be seen that the lacing is held at. one point by the cutter-gripper A and at another point a short distance away by a side gripper li. The intermediate portion of the lacing between the two grippers A and l is substan- After the cutter-gripper has closed upon the lacing, as prtwiousl explained, thccamt/moves both the cuttergrip poi-A and the side gripper B, which closes upon the lacing just. as this movement begins toward the turning-in position. As the lacing passes the knives 28 and 29 it is sheared off. The continued motion of the parts carries the lacing to the turning-in position shown in Fig. 9. The lacingis then located with its axis substantially coinciding with the axis of the chuck C, which forms one-half of the turningin mechanism. At this point the cutter-grip per A rests and the lacing is in position for the turning-in process to begin.

The turning-in mechanism consists of two sets of elements-viz, the chuck C, which operates upon the exterior of the lace, and the central support or spear 43 and gripping members 44, constituting the elements which operate upon the interior of the lacing during the turning-in process.

The chuck C, which will be clearly seen from reference to Figs. 2, 3, 4, and 8, is comosed of a barrel 60, provided with slots, in which slide the four longitudinal members or jaws 61, which-have their inner surfaces 62 serrated, checkered, or roughened, so that a proper contact with the lacing on the exterior of the spear or central support 43 is obtained and all movement of the lacing longitudinall of the chuck is prevented. The barrel is carried on a bracket 63, attached by screws 64 to the frame 0..of the machine. The longitudinal chuck-jaws 61 are pressed inwardly toward the center of the barrel by the flat springs 65 and 66, which are fastened to proj ections 67 and 68 on the barrelof the chuck. This arrangement of springs permits the chuckjaws 61 to exert a yielding pressure upon the lacing. The chuck-jaws 61 are each provided on their left-handends, as seen in Fig. 18, with projections 69, which extend beyond the end of the barrel 60 of the chuck and contact with a cam 70, which is mounted upon the barrel 6f) of the chuck and is free to rotate about the longitudinal axis of the said chuck. The cam 70 on the barrel 60 is operated by a carp-slot in the plate-cam c, this cam also being provided with the dam-slot 913, which operates the gripping member 12 of the cutter-gripper A, heretofore described. By proper timing of the cams the chuck-jaws 61 are closed at the moment the lacing is carried into position and thereafter by their serrations prevent any longitudinal movement on the part of the lacing as it is dilated or distended by the action of the interior turning-in members.

The interior turning-in device, which as a whole I have designated 1), consists of the spear 43 and spear-grippers 44. The spear is shaped as shown in Fig. 5 and has at its ends a conical-tapered portion terminating in a point for insertion in the end of the tubular lacing. Back of the conical portion is a constricted portion or neck. The insertion of the spear in the end of the tubular lacing serves to distend or dilate that end of the lacing, as hown in Fig. 9, where the spear has just been inserted. The spear-grippers 44 serve to pinch the end of the lace against the neck of the spear behind the point of greatest diameter of the said spear-head, as seen in Fig. 10. The position of the parts just before the speaigi'ip pers 44 inch the end of the lacing against the neck 0 the spear 43 is clearly seen in Fig. 9, the two gripping members of the cutter-gripper A having just separated to permit the movement of the spear into the end of the lacing. I have beveled the adjacent edges of the grippers 1.0 and 11, so that the points of the spear may be inserted slightly in the extreme end of the lacing before the time when the said grippers 10 and 11 begin to separate.

In Fig. 10 it will be seen that the speargrippers 44 have pinched the end of the lacing against the neck of the spear and that the s ear and spear-grippers are about to continue their forward movement to turn in the end of the lacing. While this turning-in movement of the interior turning-in memhers is taking place the chuck members are in contact with the exterior of the lacing and prevent the longitudinal movement of that portion of the lace which lies within the chuck when the parts are in the position shown in Fig. 10, but allowthe portion which lies to the left of the chuck, as seen in Fig. 9, to be turned in. The spear 43 and speargrippers 44 continue to move together until the position shown in Fig. 11 is reached, when the turnin in is completed. The chuck-jaws 61 an" the spear-gri pers 44 are then released, and the latter no onger pinch the lacing against the neck of the s ear, but tend to spring apart and to distent the end of the lacing and hold it against the roughened surfaces 62 of the chuck-jaws 61, so that the turned-in portion of the lacing slips off the end of the spear and is not turned right side out again as the spear and spear-gri pers retreat. The lacing is then left in tie shape shown in Fig. 22, with the portion i {turned toward the end of the lacing 1n the po sition in which it has been left by the speargrippers. This portion i serves as a dam or obstruction to prevent the cement or st1lfcningmaterial flowing into the body of the lac The movements of the interior turning-in members ust described are imparted to them by the following mechanism: The spear 43 is mounted on the end of the spcarhold(n'.74, which consists of a rectangular piece of metal having on its under side a slot 75 (see Fig. 5) for the reception of a slide 76. (Shown in dotted. lines in' Fig. 5 and in elevatioirin Fig. 2.) The slide 76 is provided at its forward end with a cross-piece 77, having mounted thereon a pair of pins 78 just outsi e the edge of the spear-holder 74. The two spear-gri 'ipers 44 are composed ofsuitable spring metal and are fast to the sides of the spear-holder 74. They are bent, as shown at 79, so that &

the pins 78 may ride up onto the side of the said spear-grippers, and thus compress them against the neck of the spear. The spearholder 74 is slidably mounted in a groove 80 which travel in the cam-slots 91 and 92 of the cylinder-cam c on the main shaft 1). The

link 87 is attached to the spear-holder 74 by a pin 93. The link 88 is attached to the slide '76 by a corresponding pin 94. A slot 95 is formed in the spear-holder 74 and permits a differential movement between the spearholder 74 and the slide 76. The cam-slots 91 and 92 are so designed that the spear-holder 74 and the slide 76 move forward together at the beginning of the stroke until the spear 43 has entered the end of the lacing and the ,machme' has reached the position shown in Fig. 9. .The slide 76, having thereon the 9 pins 7 S, is then moved forward to compress the spear-grippers 44 against the neck of the spear 43. This movement of the 'slide 76 relative to the speanholder 74 is permitted by the slot 95. The parts are then in the position shown in Fig. 10, and the slide and" s mar-holder then move forward together to the position shown in Fig. 11, the actual turning in of the lacing being performed during this movement of the interior turning-in members. After the turning'in is conn'iletcd the slide 76 starts back, first rcleasii'ig the spear-grippers and the portion of the lace held between the points of the spear-grippers and the neck of the spear, the parts then assuming the position shown in Fig. 12. Thereafter the SPOtIT-llfiltlOI' and slide move back together to the starting position, in which they rest While certain other opcrations upon the lacing'are taking place.

have not shown or described the pai'ticular shape of the grooves in the cylinder- -am (1 because the design of such a cam is a matter of mere mechanical skill and forms no part of my invention.

Having now described the means by which the lacing is cut oil and moved to the turning-in position and the means by which the portion of the lacing which extends beyond the end of the chuck is turned in, I will now describe the transfer of the lacing to the dies, that being the point at which the lacing re ceivcs the composition which serves to stiffen and harden the tip under the action of the dies. The transferof the lacing from the chuck C to the dies is accomplishci by means of a group of elements which [will call for Th e ' ing pivoted at 603 to the carrier-arm 96.

convenience the lace-carrier and designate by E. The lace-carrier E (see Figs. 52, 3, and 20) consists of a carrier-arm 96, which is pro-- vided at its upper end with the jaws 97 and 98 and is fast at its lower end upon the sliding rod 99. A set-screw 100 serves to adjust the position of the carrier-arm 96 relatively to the said sliding rod 99. The sliding rod 99 is mounted in the frame a of the machine (see Fig. 2) and is slid in the direction of its longitudinal axis by means of the cam-lever 101, pivoted at 102 to the frame a of the ma chine, the said cam-lever 101 and the sliding rod 99 being connected by a link 1025 and a balhand-socket joint 104, so that the sliding rod 99 has the capacity to rotate about its longitudinal axis as well as having the sliding movement previously described. The canilever 101 is provided with a cam-roll 1010,

which moves in a cam-groove 1011 in the cylinder-cam c of the main shaft 12. The rotary movement about the axis of the sliding rod 99 is imparted to it by means of the cam-le- 'ver 105, pivoted at 106 to the frame a of the machine and operated by a cam-slot 420 in the side of the plate-cam (See Fig. 1..) end of the cam-lever is connected by a link 107 to an arm 108, fast on the sliding rod 99. The movcn'ient of the cam-lever 105 pulls down the end of the arm 108 and causes the carrier-arm 96 to be rotated about the longitudinal axis of the said sliding rod 99.

Referring now to Figs. 3, 9, and '35, l will explain the interaction between the side gripper B and the lace-carrier E by means of which the jaws of the said sidegrippcr B are opened to release the lacing, and those of the lace-carrier E are closed to seize the lacing. the various actions taking place at the re quired times. When the machine is in the position shown in Figs. 1 and 3-that is, at the time when the lacing is being fed into position ready to be seized by the side gripper and brought to the turning-in position---thc jaw of the side gripper is opened, as will be clearti seen in Fig. 3. When the said jaw 37 is closed by. the cam-piece 40 (see Fig. 19) upon thclacing, the said side gripper B moves forward to the turning-in position and is followed in this movement by the lace-carrier E, which is rotated about the slide-rod 99. As the lace-carrier E rotates the upper edge of the spring 600 catches against the pin 601, (see Figs. 20 and 25,) so that the spring'600 is hcld away from the cam-piece 602, which is formed integral with the movable jaw 98 of the lace-carrier l9, the said cam-piece 602 be- As soon as the spring 600 is held away from the cam-piece 602, against wvhich it normally rests, the spring 604 pulls down the said ca1npiece and closes the jaw 98 against the lacing. Later when the spring 600 snaps back against the back side of the cam-piece 602 the jaw remains closed wing to the shape given to the milieulacing 'i.

. connected said cam-piece 602. For thepurpose of opening the jaw of the'side gripper 13,1 provide a pin 605, (see Figs. .3 and 25,) which contacts with the forwardly-projecting portion 401 of the cam-piece 40, causing it to move slightly about its pivot and open the jaw 37. As soon as the side gripper B is out of the way the lace-carrier is caused to slide longitudinally by means of the sliding rod 99, withdrawin from the chuck C the turned-in end of the acing which has just been released. When the position shown in Fig. 1 3 is reached, a rest in the cam-groove causes the .lacecarrier to cease its lon itudinal movement. At this point the end 0 the cam-lever is depressed by the rotation of'the plate-cam f, and the lace-carrier arm 96 is caused to revolve aboutthe longitudinal axis of the sliding rod 99 until the end of the lace t' lies in the die F, b which character I group 0 members which compresses the turned-'n end of the lacing to form the finished tip. The lace-carrier E has also a further motion which I will describe later'in connection with the cement-applying apparatus and the dies F. The lacing t, being now in the osition indicated in Fig. 14 and held firm y by the lace-carrier E, as previously described, is filled with cement or other suitable flowing substance by means of a cementapplying apparatus G. Thiscement-applying apparatus G consists, essentially, of a suitable cement-can 109, which I have shown as surrounc'led by a steam or water jacket 110, the cement used being usually of such a nature that it is necessary to keep it warm while it is being applied. The cement-can is by a flexible connection 111 with a pump-cylinder 112, which is provided at its forward end with a tip 113 of convenient size for insertion in the dilated end of the Within the pump-cylinder is a piston 114, which is of a size to completely fill the cylinder back of the point of entrance of the flexible connection 111 when the parts are in the position shown in Fig. 6. The forward end of the piston 114 consists of a wire 115 of a diameter substantially equal to that of the interior bore of the pointed pump-tip 113. This piston 114 is stationary, being attached at its rear end by a pin 116 to a cross-piece 117, which is screwed or otherwise suitably attached to the frame a of the machine at 118. I provide the plate 1.17 with slots 119, so that a slight adjustment of the position of the piston may be had, if desired. The pump-cylinder 112 is mounted on a slide 120 with capacity to slide in the frame of the machine. The siide 120 is given a longitudinal movement by means of the groove 12] in the cylinder-cam c, which groove moves a cam-roll 122, pivoted on a cam-lever 123, which is itself pivoted to a bracket 124 on the frame a. of the machine.

The upper end of the sald cam-lever 1 23 is designate the ters the bore of the pump-cylinder connected by a link 125 to the said pump-slide 120. It will thus be seen that the pumping action of the pump occurs by reason of the fact that the pump-cylinder is moved, while the pump-piston remains stationary instead of in. the ordinary manner, in which the piston is movable and the cylinder stationary. he

forward end of the pum -piston 115 always remains ver close to t e distended end of the lacing w ien in the position shown in Fi 6 and 14. The interior of the pump cylin er 112 and tip 113 thereof is filled with the ocmentitious material by gravity and also by suction during the forward movement of the pump-cylinder as it is inserted into the distended end of thelacingi, the tip 113 of pump cylinder 112 being closed during the first part of this movement by the forward end of the pump-piston or wire 115. When the camc causes the pum -cylinder to begin its backward motion, t e mainportion 114 of the pump-piston fills the tip 113 of the pump-cylinderwith cement. The continued backward movement of said pump-cylinder causes the Wire 115 to enter the tip 113, thus cutting off the further admission of cement from the reservoir. The further backward movement of the pump-cylinder forces the cement 1n the tip out of the said ti into thedistended portion of the lacing. s soon, however, as the small portion of the pump-piston 115 choint only so much of the cement is therea ter forced contained in' the conthe further movement ump-piston servuous cement back It will thus be into the lacing as is traeted bore of the tip, of the enlarged part of the ing only to force the super into the cement-can 109. seen that by adjusting the the pump-piston 144 by means of the screws and slots 118 and 119, respectively, I am enabled to regulate or measure with great exactness the amount of cement which is deposited within the end of the lacing. By reason of the fact that the cement is-cjected during'the backward movement of the pumpcylinder the cement is laid evenly the entire length of the tip, thus insuring it even distribution. As soon as the pump-cylinder point 113 is withdrawn from the lacing the lacecarrier E is moved again by the sliding rod 99 and cam-slot 1011, so that the end of the distended portion of the lacing is flush with the left-hand side of the die F, as seen in Fig. 16. i

The die F is constructed in the following manner: Or the frame a of the machine there is located a block 130, which serves to support and guide the various members composing the die. The die proper is made in three parts-namely, the bottom die member 138, formed integral with the block 130, the top die member 131, and the side die member or guide 132. The top die member is carried upon a spindle 133, guided in the fixed position of izo ' block, whieh is forwardly projeeted at the l a eonsiderable portion of the eyele of the ma.-

l: have found in the operation of my machine that son'ietimes the lining i in being transferred by the laee-earrier E to the eement applying position becomes slightly bent or otherwise distorted, so that its end does not exactly register with the center of the. line of the eement-applying apparatus. l have therefore timed the ram 9. so that the side die is moved toward the other two die members and pushes the laeing into the proper position before the tip of the eements applyin g apparatus enters the dilated end of thesaid hiring. Afterward just prior to the time when the top die 12H descends to ronipress the laeing into the bottom die lit) the said side die member completes its movement toward the right, thus assisting to hold the lacing in proper position as the top die descends.

In order that the laeing'i may be released from the lace-carrier i after the dies have closed upon the tip of the lacing, 1 provide an arm or hook 620, pivoted at (321 to the frame a of the niaol'iine and operated by a camgroove (522 and eam-roll (323 The raingroeve (S22 is cut in the ram g, this being the cam described in e onneetion with Fig. 24, which operates the side die 132. The tip of the hook or arm (20 contacts with the top edge of the movable jaw US of the lace-earrier and opens it at the desired time.

l have timed the cam]; which operates the.

top die, so that the die remains closed during ehine in order that the eenient or other stiffening' material used may be given sutl ieient opportunity to set or harden.

,i'hile l have not deseribed partieularlv the eonstruetion of the various ams which o; ate the separate groups of elementr's whirh perform the different operations, sini'e l believe the timing of these cams to be only a matter of nieehanieal skill, nevertheless it will be seen that the various inns are timed so that the operations take place suhstantially in the order describrn'i and the brohel portions of th eyete of movement of the maehine are given to each of the various operations. It. will thus be seen that thetaterior tiirning-dn members i) are standing still during the time in whieh the other operai allowingthe next length of hiring to be fed into position -uamely that in which the eeinent filling of the tip, its eompressioii, and the return of the lace-carrier to the position shown in Fig. 1 is taking pl'aee. This proper int-errelatimi of the different groups of meritanisin is all eared for by the timing of the different parts.
